Provided are a method for measuring the phototoxicity or photoallergy of a test substance without using animals and a reagent for use therein. The method for measuring phototoxicity or photoallergy includes reacting a test substance with an organic compound that is an N-(arylalkylcarbonyl)cysteine or an α-N-(arylalkylcarbonyl)lysine under irradiation with ultraviolet light; reacting the test substance with the organic compound without irradiation with ultraviolet light; determining the depletion of the organic compound after each reaction by an optical measurement; and detecting phototoxicity or photoallergy from the difference between the depletion of the organic compound after the reaction under irradiation with ultraviolet light and the depletion of the organic compound after the reaction without irradiation with ultraviolet light.
本发明提供了一种不使用动物而测量受试物质光毒性或光过敏性的方法以及用于该方法的试剂。这种测量光毒性或光过敏性的方法包括:在紫外线照射下,使受试物质与 N-(芳基烷基羰基)半胱
氨酸或 α-N-(芳基烷基羰基)赖
氨酸的有机化合物反应;在没有紫外线照射的情况下,使受试物质与有机化合物反应;通过光学测量确定每次反应后有机化合物的损耗量;根据在紫外线照射下反应后有机化合物的损耗量与在未用紫外线照射的情况下反应后有机化合物的损耗量之间的差值检测光毒性或光过敏性。
